srncrrrcArIoN forming part of Lettersratent No; 650,099, atea May 22,1900. Application fil'ed November 10,1899.I Serial No. 736,511.(No-model.)

Beit known that I, HENRY H. SESSIONS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Car Construction, of which thefollowing is a specification.

My invention relates particularly to an improvement in draft-rigging andbniiing mechanism for use more especially in freight-car Construction. V

My primary object is to provide improved means for yieldingly securingthe draw-bar to the draft-beams and sills of the car-body, and alsocoacting builing mechanism which shall replace the ordinary dead-blockto the extent that a dead-stop shall be completely avoided underconditions short of a very severe accidental collision.

In the accompanying drawings, Figure l is a broken plan view of thesubstructure or sills of a car-body and the draft-beams thereof equippedwith my improvements; Fig. 2, a broken vertical longitudinal section online 2 of Fig. l; Fig. 3, a plan section online 3 of Fig. 5; Fig. 4E, avertical section on line 4 of Fig. 3; Fig. 5, a transverse verticalsection on line 5 of Fig. 2; and Fig. 6, a composite sectional view, theleft-hand portion beingytaken at the line 6 of Fig. 2 and the'right-hand portion being taken at theline 6 thereof.

A A' represent the center sills; B, the end sill; B', a blockjoining thecenter sills above the body-bolster, the ends of said block being setinto recesses in said sills, as indicated i in dotted lines in Fig. 1;B2 B3, the upper and lower metallic members, respectively, of thebody-bolster; C C', metallic draft-beams, preferably in the presentconstruction of channel form; D, the draw-bar, provided at its head withan upwardly-projecting lug or horn D' and supported by carrier-yokes EE; F, a horizontally-disposed channel-bar having downturned flanges andextending from the end sill to the block B', its web portion occupyingthe space (about nine inches wide) between the lower portions of thecenter sills and its flanges being secured to the webs of the draft-beams by rivets a; G G',short transversely-extending angles riveted tothe web of the channel-bar F and secured by bolts b `b' to the end sillB and block B; H H', me- `tallic 'draft-plates or draft-spring pockets`secured to the webs of the channel-bars C C' by rivets c, Fig. 3, saidplatesbeing provided with longitudinal ribs or guides c', with verticaltransverse recesses c2, and with outturned lower flanges c3, Fig. 5,which latter extend beneath the lower flanges of the channel-bars C Cand are secured thereto by rivets c4 and also by certain of the boltsc5, which serve toV securethe draft-beams to the center sills; I, Figs;3 to 5, a fixed block having its ends set into the recesses c2 andserving to trans, vmit pressure to and from the draw bar springs; J, aspring-retaining loop or clevis secured to the inner end of thedraw-barby rivets d; J', a spring-bearing plate for said loop; J2 J3,bnfting and draft springs, re-

spectively, the former being confined be-` tween the block I and theouter end of the slot formed by the loop J and the latter between theblockI and the inner end of said slot; K, a movable butter-head orplunger which lits within a sleeve or bushing K', set

in to a block K2, and bears against a powerfull ybuffer-spring K3, thelatter in turn bearing against a facing or spring-bearing plate K4 setinto the front face of the end sill B; K5, a

`retaining face-plate provided with a perforation through which theouter end of the stem or plunger K projects and which engages a y collare on the plunger to hold the latter in place, and KG a chaiing-plate onthe lower face of the sill B directly above the drawbar.

As shown in Fig. 2, the inner or rear end of the channel-bar F abutsagainst the metallic member B2, and the latter rests upon the'draft-beams C C'. The butter-head-engag` ing lug D' of the draw-bar ispreferably normally out of contact with the buffer-head K, and said lugcomes into contact with said buer only after the spring J 2 has beencompressed a certain distance. spring K5 coacts with the spring J 2 toprevent the lug D from reaching a dead-stop under normal workingconditions.

It will be observed that force is transmitted from the draft-beams tothe car-sills, and vice versa, through the bolts c's and also through'The' powerful IOO ` iipturnedanges which embrace the lower bar is'forcedin it pressesthe spring J2 against y erably vcut out or recessed toreceive portions turned flanges riveted to said draft-beams and theangles G G', the lattervirtually forming a part of the channel-bar F,which isthu's set in between the center sills, the'end' sill B,an'd`block B.

From the foregoing description it'wi'llzbe understood that when thedraw-bar is drawn frw'ard the rear end of the loopJ presses the spring J3 against the rigidcb'lo'ck I^,'fromij whence the moving force isdistributed through the plates H H to the draft-beams, and from thencedirectly to the car -sills through the bolt-s c4, and indirectly tosaidA sills through the channel-bar F and angles G G', the latterangleserving particularly in` the draft action and theformer in4 thebuing s action. On the other hand, when the drank.

theblockl', .from whence the force is trans-` mitted tothe sills, asstated. Aftera certain compression of the spring J2 vthe spring K3 iscompressed and transmits force directly to they sills of the car. y

By'preference the carrier-yoke E passes beneath the flanges c3 of thedraft-plates H H', asY shown in Fig. 5, and is provided with flanges ofthe draft-beams. As appearsalso from' the last-named ligure, thehorizontallydisposed clevis J, which occupies a vertical plane, has awide enough horizontal channel or slot to receive the block I. withoutcontactfd ing therewith, the draw-bar and clevis being siiported andguided by the carrier-yokes E The flanges of the channel-bar Fare prefofthe draft-plates H H', as appears in Figs. 2,5-, and 6, as such aconstruction relieves to a. large extent the shearing action on therrivetsjand bolts of the draft-plates.

No. limitation is intended by the detailed description given except asshall` appear from the appended claims.

What l claim as new, and desire to secure by Letters Patent, is-

l'. `Ina car, the combination with the sills, draft-beams, and a blockjoining the center sills, oa channel-bar providedwit-h down-y secured atits outer end to the end sill, and at its inner end to said block, boltconnection between draft-beams and center sills, a drawbar, and springconnection between draw-bar anddraft-beams, substantially as and for thePurpose set forth.
